New Software Changes Wireless Technology Functions on Demand

Imagine an electronic gadget, like your cell phone, evolving into the next generation of communication devices through the use of radio technology. From the prospect of downloading software to adapt a cell phone into a video camera or MP3 player, to the idea that satellites could interact and share data directly by configuring themselves, the possibilities for SDR are without bound.

Researchers at NASA's Goddard Space Flight Center in Greenbelt, Md., are so enthusiastic about SDR that they have recently built an SDR test-bed - providing the necessary foundation for investigating SDR technologies and techniques. This test-bed allows for the rapid, low-cost development of communication and navigation algorithms that will be used in upcoming technology experiments, and eventually, in missions.

Software Defined Radio is a relatively new wireless technology based on the familiar radio technology that has been used for many years. Traditional Earth-based radio technology involves the transmission of a signal, typically "analog" speech or music, as electromagnetic waves using a single purpose radio transmitter. The electromagnetic waves travel through the air until they encounter a radio receiver that has been tuned to receive the right frequency. This receiver processes the signal and sends the result to a speaker. You then hear whatever was broadcast from the radio station. In SDR, the transmitter modulation is produced by a digital signal processor (a form of computer) to produce digital signals, the signals are then converted to "analog" and sent to the transmitter's antenna. The receiver uses a computer to recover the signal intelligence.

Developing Linux Is Essential To Intel's Success

The dominant position of Intel in the server processor market is likely helped by the company's consistent strong support for Linux. Based on the W3Techs chart below, Linux is almost as popular as Windows-based servers are.

Firefox OS heading for Africa — and the U.S. too

Orange announced a $40 “Klif” Firefox OS phone for Africa, and Mozilla says it’s working with Verizon Wireless and others on Firefox OS feature phones.
There’s still no evidence that Mozilla’s HTML-focused Firefox OS has made much of a dent in the world smartphone market, where it has been focused on low-end devices sold primarily to emerging markets. Yet, Firefox OS still leads the way among upstart, Linux-based mobile operating systems, and will soon be available in more than 40 markets, this year, on a total of 17 smartphones, according to its latest stats. Meanwhile, the very first Tizen (Samsung Z1) and Ubuntu (BQ Aquaris E4.5) phones have only just shipped, and Jolla’s Sailfish OS based Jolla phones are still mostly limited to Europe.

Why large companies use open source ERP

The main reason larger companies use open source Enterprise Resource Planning (ERP) systems is because they are cheaper and easier to customize.

New Ubuntu Phone Separates the App from the Data

As CIO Journal has noted, Mr. Shuttleworth envisions the rise of an Ubuntu-powered phone that runs desktop grade applications and plugs into peripherals such as large displays and keyboards. In other words, he is working to achieve true mobile-desktop-laptop convergence — the only computer you need, in your pocket, all the time. He tried to raise $32 million to fund development of such a phone, known as the Edge, in a widely publicized crowdfunding campaign on Indiegogo. The campaign ended in 2013, short of its goal.

Korora 21

My install went quite well, I had no problems and the install itself was relatively speedy. Bear in mind, however, that I have used the Anaconda installer often in the past. So I’m quite familiar with how it is laid out and what it has to offer. Use the Fedora install guide for Anaconda I linked to above if you’re new to it as it might save you some time when installing Korora 21.

How to run Linux and Chrome OS on your Chromebook

Chromebooks are pretty darn handy. Even some hardcore Windows users now acknowledge that a Chromebook might be just what you need for work. But, as great as Chromebooks are, and as much progress as Google has made in getting "Web-only" apps such as Google Docs to work offline, there are still times that you want an application that's only available off-line such as the LibreOffice office suite or the GIMP photo editor. For those times, it's darn handy to be able to run a Linux desktop on a Chromebook.
